Built from cobalt vanadium high speed steel with a bright, uncoated finish, this bit delivers consistent cutting performance across a range of ferrous and non-ferrous materials. It measures 0.266 inches (17\/64 inches, Letter H) in diameter with a 130-degree split point and a parabolic flute geometry. The straight-cylindrical shank fits standard drill chucks, and the web-thinned, tapered web configuration reduces thrust requirements at entry. Licensed machinists, tool-and-die technicians, and fabrication professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for screw machine, production drilling, and general fabrication environments where compact drill length and reduced deflection matter. Its universal tool performance rating covers cast iron, hard materials, non-ferrous metals, stainless steel, and steel. The 3xD flute-to-diameter ratio and parabolic flute design support efficient chip evacuation in short-hole drilling. Maximum drilling depth is 0.900 inches (22.00 mm). Applications span CNC machining centers, manual drill presses, and hand-held drilling in metal fabrication or maintenance settings where a rigid, short-body bit outperforms standard jobber-length geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt vanadium high speed steel construction for heat resistance and edge retention in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e130-degree split point reduces walking and lowers thrust at drill entry\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile promotes efficient chip evacuation in short-depth bores\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration minimizes cutting resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body reduces deflection and improves rigidity in tight-clearance setups\u003c\/li\u003e\n  \u003cli\u003eMeets DIN, ISO, and BS specification designations for dimensional and performance conformance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw machine length drill bit in the WALTER-TITEX Series A1148, suitable for use in standard straight-shank drill chucks on CNC machining centers, drill presses, and screw machines where a 0.266-inch diameter bore is required in cast iron, stainless steel, steel, hard materials, or non-ferrous metals.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with metal-cutting operations. Secure the shank fully in the chuck and verify runout before drilling. Power down all equipment and lock out energy sources before changing or inspecting the bit. Do not exceed the recommended maximum drilling depth of 0.900 inches without retracting to clear chips, particularly in stainless steel or cast iron.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.266 inches (17\/64 inches, Letter H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-29\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.900 inches (22.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0623 inches (1.58 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Vanadium High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: Universal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.00087 to 0.00000 inches (-0.022 to 0.000 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO, BS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1148\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5153721\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51740018213170,"sku":"5153721","price":29.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_fb00580f-ab3e-437a-9cd8-1a13456bf193.jpg?v=1788821503","url":"https:\/\/voomisupply.com\/products\/walter-titex-5153721-screw-machine-drill-bit-0-266-in","provider":"Voomi Supply","version":"1.0","type":"link"}
